Determines whether the preview pane is being used. The preview pane is only used to display a subfile in a container file. When it is enabled, the viewing area is divided into two panes: one pane displays the contents of the container file, the other displays the contents of the selected subfile. For more information, see VAPIMWP_VIEW_SETPREVIEWPANE . This is a parameter of the VAPIM_VIEW message.
#include <kvvapi.h> SendMessage(hWndVAPI, VAPIM_VIEW, VAPIMWP_VIEW_GETPREVIEWPANE, (LPARAM) (BOOL*) lpbPreviewPane );
| Argument | Description |
|---|---|
hWndVAPI
|
The handle of the VAPI window. |
lpbPreviewPane
|
A pointer to a flag that returns TRUE or FALSE, depending on whether the preview pane was returned. Only container files use the preview pane. |
SendMessage() returns TRUE if the call succeeds, in which case lpbPreviewPane returns TRUE or FALSE.SendMessage() returns FALSE if the call fails (for example, if there are invalid arguments or if no document is open), in which case lpbPreviewPane is undefined.|
